Weird Probelm-Internet

[Rem]

THis is weird, My clan leader registered his domain at 123reg, the domain is www.pantscs.co.uk he give me his 123reg log on details so I could change the DNS server details on the web conrtol pannel. So the website now works!!!! For every1 except me, everytime I go on www.pantscs.co.uk It comes up with this 123reg site, I did the DNS stuff on firefox, however on 3 browsers (IE, Firefox, Opera) i get the same site!! IV deleted all net files, cleared SSL cahce, deleted cookies, files everything.
It works fine on my other PC but I want to open it on this (my main) PC.
Any suggestions??

EDIT-Also just tried cmd.exe-ipconfig /flushdns but it said it failed??

Could it be that I have a router with a static ip??

Other forums are stumped by this problem, i dont want to have to reset my router (loads of port configs) lets see if you guys can do ya stuff!!!

I'm not sure where you are in the windows menu, but if there is an option to "log on as a new user," select that. And you should be set to go.

What happens on the login screen, someone types in the wrong name and password.

From then on, Windows keeps trying to send it every time you log in.
